Last week my Maths lessons were focused on number bonds to 100. The students in my Maths group were already very familiar with the bonds to 10, so I decided to take them a step further. As is always the case, some caught on straight away, while others took a little more time and revision.

If...Then...Graphic Organiser

I used an If... Then... Graphic organiser to demonstrate how number bonds to 10 are related to number bonds to 100. For example, knowing 7 + 3 = 10 is related to 70 + 30 = 100. We then used blank number lines as a way to explore some of the bonds.

For the second lesson we used the If... Then... graphic organiser to explore how a knowledge of number bonds to 100 can help with working out change from $1.00. Students then used blank number lines to find change from $1.00 and a second worksheet with some examples of buying items at "Tessa's treat store". I was able to work more closely with some students to ensure they understood the process of using the blank number lines. We also used some base 10 blocks to demonstrate a common mistake students were making which resulted in bonds to 110 instead of 100.

In the third lesson students played concentration with number bonds cards, where they had to find the pairs of numbers that add to 100. This was a great way to reinforce the pairs and an activity I will come back to in future lessons.
The worksheets for this lesson can be downloaded for free at my Teachers Pay Teachers store. The package includes:
